hey, I was told to use super duper in order to back up my drive... I want to back up, so that i can create another partition, just backing up to be safe.. so anyways, i want to use super duper, how do i set it up. should i just copy the entire HD, all files, and that will be a full backup? Is it possible to back up to one dvd, or two dvd's? or is that not possible?
